TurboTax does not have copies of W-2's, see the following on how to get a copy of your W-2.

Although you may have previously filed with us, we didn't save a copy of your W-2. If you used our mobile app to snap a picture of your W-2, it's not saved on your device.

Your best bet is to ask your employer or payroll department for another copy of your W-2.

Here are some more options:

• Order a copy from the Social Security Administration. It's free if you need it for Social Security-related reasons; otherwise, it's $86 per request.
• Order a full copy of your return from the IRS for $50, which will also include your W-2.
• Wage and income transcripts are available from the IRS free of charge.  They're not exact copies, but they contain everything on your W-2 except the state and local information.
